Quick And Dirty Parameter Tuning
Submitted by

Have you ever had a parameter value that you needed to tune
interactively but didn't want to spend the time to make that
possible? You can use your debugger to do this easily.

Original code:

thePhysics->ConstrainPosition(0.05,0.04,0);

Tunable code:

static float xstr = 0.05;
static float ystr = 0.04;

thePhysics->ConstrainPosition(xstr,ystr,0);

By setting a breakpoint and modifying the value of the statics
you can tune the values in a persistant fashion (i.e. they won't get reset
between invocations of the code within the same debug session) without
recompiling your .exe.
